Chapter 1 - Operation

General Operation

Pre-Operation Inspection

Safety should be the n   umber one thought on every operator’s mind.  Three factors should 
exist for safe operation: a qualified operator, well-maintained equipment, and the proper 
use of this equipment.  

This chapter contains information regarding the safety and operation of Stellar® 
manufactured EC Series Telescopic Cranes and should be read and understood 
completely by everyone working with or near the crane before putting the unit into 
operation.  

 

 

 

Failure to follow operating, maintenance, or safety instructions can result 

in death or serious injury.

It is the responsibility of the owner to instruct the operator in the safe operation of the 
equipment and to provide the operator with properly maintained equipment. 
 
 

 

 

Stellar® Crane operators must conform to the qualifications specified in 

ANSI B30.5 - Chapter 5-3 Operation.  Trainees or untrained persons shall be under the direct 
supervision of qualified persons.

Operators shall consult with the owner of the equipment regarding current safety 
regulations and required personal protective equipment. 

Please take note that Stellar Industries, Inc. is not liable for accidents incurred by the crane 
because of non-fulfillment from the operator’s side of current rules, laws, and regulations.

Before operating the equipment, make sure all regular maintenance has been performed.  
Each day, inspect the crane for all of the following: 
• Vehicle for standard checks such as proper tire inflation and fluid levels.
• Parking brake operation.
• Hydraulic reservoir for proper oil level.
• Hoses and gearboxes for evidence of oil leaks.
• Crane controls for excessive wear, cleanliness and proper operation.
• Operational aids such as decals for placement and legibility.
•  All securing hardware such as cotter pins, snap rings, hairpins, and pin keepers for proper 

installation.

• Crane hook and other loose parts for damage to structures or weld.
• Anti-two block switch for proper function.
• Wire rope for broken wires, extensive wear, distortion, and heat damage.
• All safety guards for proper installation.
Replace/repair as necessary prior to operation.  For a more detailed checklist of scheduled 
inspection points, refer to the Stellar® Crane Inspection Log.  This document is an essential 
guide for the daily, monthly, quarterly and annual inspection tasks that will help maintain 
the quality of your Stellar product.
